Abstract: PROBLEM TO BE SOLVED: To always reproduce music high in sound quality regardlessly of a sound recording source. SOLUTION: When a recording source is analog (digital) in recording, a system controller 54A inputs audio data AD (audio data DD having effective bit length of 16-bit outputted from a DIR 52) having effective bit length of 20-bit outputted from an A/D converter 51 to an encoder 56, outputs information indicating effective word length = 20-bit (16-bit) to the encoder 56, and records it in an optical disk 58 with audio data.  At the time of reproducing, restored audio data D0 outputted from a decoder 59 is inputted to a data correcting section 80, when effective word length information restored by the decoder 59 is 20 bits, the data is outputted to a D/A converter 60 as it is, when it is 16 bits, the audio data D8 corrected by passing through a quantization distortion reducing circuit 83 in which effective word length is expanded to a lower order side by 4 bits is outputted to the D/A converter 60.

IPC: C23C30/00
Filed: 1994-05-17
Abstract: PURPOSE:To strengthen the boundary between columnar crystal grains, to suppress the radial growth of the columnar crystal, to refine the crystal and to impart seizuring resistance and high hardness to a sliding face structure at the time of forming a layered sliding face structure (metallic crystal aggregate film) on the surface of a base material by plating, by incorporating B into the structure. CONSTITUTION:A metallic film is formed with the metallic crystal aggregate having many columnar metallic crystals 5 and 6 grown from the outer peripheral surface 3 of a base material 2. In this case, >=0.01wt.% B is incorporated into the structure. Meanwhile, the area ratio A1 of the crystals 5 and 6 is controlled to <=30%, and the tips are preferably formed of pyramidal crystals 9 and 10. When a fixed amt. of B is incorporated into the crystals 5 and 6 and granular metallic crystal 7 of the structure 4, the B is deposited in the grain boundaries 8 between the adjacent crystals 5 and 6, etc., to strengthen the boundaries. Besides, since the radial growth of the adjacent crystals 5 and 6 is suppressed due to the preferential deposition in the grain boundary 8, the crystals are refined, and high hardness is imparted.

Title: Apparatus for film formation using glow discharge
Inventor: ADACHI GENICHI
IPC: C23C16/455
Filed: 1981-08-18
Abstract: PURPOSE:To obtain an even-thickness film through glow discharge by distributing a plurality of gas ejection nozzles in the longitudinal direction of a gas leading pipe and furnishing a reaction room with evenly-distributed gas. CONSTITUTION:To evenly eject gas from a plurality of nozzles two methods are considered: nozzles are positioned at the same interval with the area of each nozzle increased correspondingly with increasing distance from the supply source; or nozzles having the same area are positioned with the interval increased with increasing distance from the source. In this constitution the portion of a gas leading pipe at which the gas pressure is high provides small conductance, while the portion with low pressure of gas provides large conductance; therefore, the amount of gas ejected from each ejection nozzle along the pipe becomes virtually the same, thereby generating even plasma around a sample to yield the accumulation of a film with even thickness.

Title: Pll circuit
Inventor: OGASAWARA UICHI
IPC: H03L7/14
Filed: 1991-05-31
Abstract: PURPOSE:To reduce a synchronization lock time when a reference input pulse signal is tentatively lost and then restored. CONSTITUTION:A phase check circuit 20 checks whether or not the detection state of the relation of phases by a phase comparator circuit 1 is adequate. When the result of the check indicates improper, a correction pulse generating circuit 30 generates a correction pulse signal S12 or S13 to select the detection state of the relation of the phases. A correction pulse insertion circuit 10 inserts a generated correction pulse signal to a reference input pulse signal S1 or a comparison pulse signal S7 to give the reference input pulse signal or the comparison pulse signal with a valid edge added thereto simulatingly to the phase comparator circuit. Thus, the detection state of the phase relation by the phase comparator circuit is selected so that the synchronization locking is quickened.

Filed: 1985-06-14
Abstract: PURPOSE:To raise the bonding strength between a piezo-electric ceramic tube and an electrode by providing a piezo-electric ceramic tube having electrodes made of a conductor thin layer formed by laminating Ag layer on a Ni layer on its inner and outer surfaces. CONSTITUTION:When a voltage is applied through electrodes 6 and 7 to a piezo-electric ceramic tube 3, the tube 3 contracts in the axial direction, and at the same time its inside diameter is contracted. A liquid conduit 1 is compressed thereby and a liquid is jetted from a jet nozzle 2 on the tip of the conduit 1 by the pressure. When the voltage is changed and the displacement of the tube 3 is restored, the tube 1 is also expansively restored and its internal pressure becomes a negative pressure, and therefore, the liquid from the liquid layer is supplied by suction into the tube 1. By the repeating compression of the tube 1 by the tube 3, the liquid can be continuously jetted.
